We believe that future many-core architectures should support a simple and scalable way to execute many threads that are generated by parallel programs. A good candidate to implement an efficient and scalable execution of threads is the DTA (Decoupled Threaded Architecture), which is designed to exploit fine/medium grained Thread Level Parallelism (TLP) by using a hardware scheduling unit and r...

Top-k query has been widely studied recently in many applied fields. Fagin et al. [3] proposed an efficient algorithm, the Threshold Algorithm (i.e. TA), to process top-k queries. However, in many cases, TA does not terminate even if the final top-k results have been found for some time. Based on these, we propose a novel algorithm: Density Threshold Algorithm (i.e. DTA), which is designed to m...

Traffic conditions significantly affect drivers‟ behavior that constitutes one of the principal causes of road accidents. Being able to accurately predict traffic conditions significantly improves the assessment of accident risk. Traditional approaches to traffic flow analysis use static representations of the road system and as such have limited accuracy. Dynamic Traffic Assignment (DTA) appro...

We report findings from two usability studies of digital television (DTV). A preliminary study was undertaken with eight subjects. The final study had thirty subjects. It was found that content and interface elements should be evaluated in terms of concrete and conceptual nearness with respect to all parts of the DTV experience. Additionally, several features of the DTV application interface we...

The thoracic descending aorta (DTA) was examined in 57 patients undergoing coronary artery bypass grafting (41 men and 16 women: 63.0 +/- 10.6 years old) using two-dimensional transesophageal echocardiography. An intraaortic balloon pump (IABP) was instituted in ten patients. A short-axis view of DTA was examined for intraluminal projection from the diaphragm level to the aortic arch level. In ...

BACKGROUND Although the aortic augmentation index (AI) is an attractive tool as an index of the vascular system, the association between radial AI or brachial-ankle pulse wave velocity (PWV) and severity of atheroma or arterial stiffness of the morphological central artery is unclear. METHODS AND RESULTS Severity of atheroma and aortic stiffness of the descending thoracic aorta (DTA) by trans...

Dynamic taint analysis (DTA) is a powerful technique for, among other things, tracking the flow of sensitive information. However, it is vulnerable to false negative errors caused by implicit flows, situations in which tainted data values affect control flow, which in turn affects other data. We propose DTA++, an enhancement to dynamic taint analysis that additionally propagates taint along a t...

Nonadiabatic excited-state molecular dynamics (NA-ESMD) simulations have been performed in order to study the time-dependent exciton localization during energy transfer between two chromophore units of the weakly coupled anthracene dimer dithia-anthracenophane (DTA). Simulations are done at both low temperature (10 K) and room temperature (300 K). The initial photoexcitation creates an exciton ...
